I am making an android kiosk pos app. The kiosk and flex devices were connected through the Network pay display app. The orders created here were printed out on a kitchen printer. While the network pay app is running on the flex device, order forms are not printed on the kitchen printer. After closing the network pay app, an order form is printed. I want to print using the kitchen printer even while the network pay app is running. I want to know how to do it.
